Abstract

Background: A Holter electrocardiogram is an effective tool to monitor cardiac arrhythmias in the general population and patients with cardiovascular diseases in particular. Data on heart rate variability characteristics as well as arrhythmia patterns in patients with cardiovascular disease are limited in Vietnam. Objective: The purpose of our study was to describe electrocardiographic changes and major arrhythmia abnormalities on the 24-hour Holter electrocardiogram in patients with cardiovascular disease. Materials and Methods: This was a descriptive cross-sectional study. The study included 178 patients with cardiovascular disease assigned to attach Holter electrocardiogram. Use the Philips Holter DigiTrak XT 5-electrode system for ECG recording and analysis. Results: Among 178 patients, the mean age was 54.6 ± 16.2 years and woman represented for 49.4% (170/142). The most common complaint symptoms were palpitations (35.4%) and 9.6% of patients have no initial symptoms. History of arrhythmias, hypertension, and coronary artery disease with rates of 46.1%, 30.2%, and 27.5%, respectively. Most of the patients in the study had a baseline Holter rhythm that was a sinus rhythm. There were 68/178 (38.2%) patients with major arrhythmia on the Holter 24-hour electrocardiogram. Supraventricular tachycardia, ventricular tachycardia, bradycardia, and frequent premature ventricular contraction accounted for 15.7%, 6.2%; 10.7% and 12.4%, respectively. Conclusions: The study revealed that in patients with cardiovascular disease who were indicated for 24-hour Holter electrocardiogram, palpitation was common symptoms. About a one third of the study patients found major arrhythmias on a 24-hour Holter electrocardiogram, in which supraventricular arrhythmias and frequent premature ventricular contraction were the two types of arrhythmias with the highest recorded rates.
